When the air outlet structure 10 is ventilated, the transposition plate 104 without the sealing plate 105 is far away from the air outlet 102, so that the gas introduced into the fan-shaped pipe 9 can enter the alkali liquor.
Further, the air outlet 102 may be provided as a one-way passage or a one-way valve to prevent lye from entering the fan-shaped tube 9.
When the sealing device 12 seals the space between two adjacent sector pipes 9, the sealing structure 13 moves along with the sealing device 12, so that the transposition plates 104 on one side of the sector pipes 9 are pushed by the sealing structure 13 to rotate and seal, the sealing plate 105 is close to the air outlet 102 to seal the air outlet 102, the transposition plates 104 on the other side are pushed by the sealing structure 13 to rotate, the sealing plate 105 is far away from the air outlet 102 to open the air outlet 102, so that the air inlet or the air outlet state of the two sides of the fan-shaped pipe 9 is controlled, the air inlet is disconnected when the new lye is replaced, and the air is simultaneously introduced into the old lye to continuously absorb and purify the air.
